As you should know, HEPA filters are those capable of eliminating dust, pollen, pet dander, mold, bacteria, viruses, and other particles present in the indoor air. Its acronym means "High-Efficiency Particulate Air", and although it is often present in most portable air purifiers, its use has also begun to spread to wider ventilation systems.

Currently, a HEPA filter that is installed in heating, ventilation, and air conditioning systems can greatly improve the quality of the indoor air, filtering all the small particles that most concern health experts. However, are there more reasons to use a HEPA filter? Here is the answer.


Why use HEPA filters in the ventilation system?

Other tempting alternatives are likely to appear before selecting a HEPA filter. However, you should know that not all offers available on the market are as beneficial or efficient as a HEPA filter. Here are the reasons:

  • HEPA filters do not produce ozone: Unlike other air purification systems, HEPA filters do not contain or produce ozone, a toxic compound that is highly harmful to human health according to the United States Environmental Protection Agency.
  • They do not work with ionization: Although some researchers have closely followed the effectiveness of ionizers on air quality, the truth is that so far there is no clear indication of the effectiveness of this mechanism, because it is unable to remove certain types of particles. So far, HEPA filters can remove 99.97% of the particles present in the air, even those as small as 0.3 micrometers.
  • MERV Certification: Most HEPA filters have a MERV 13 rating. MERV means Minimum Efficiency Report Value, and the higher this number, the greater a filter’s ability to capture particles. The MERV scale goes from 1 to 16, with 13 and 16 being the most recommended numbers.


How to start with a HEPA filter?

To successfully install a HEPA filter and enjoy all its benefits, it is advisable to apply the following recommendations:

  • Visit a hardware store or local store specializing in these types of products, to compare the best alternatives and make sure you get the HEPA filter that best suits your needs.
  • Be sure to request a review of the ventilation systems in your home, office, or business. A professional service will help you thoroughly clean the ducts and check for possible leaks. Without this review, likely, the HEPA filter will not work optimally.
  • Replace HEPA filters every 3 months. Remember that a well-maintained ventilation system, with top-quality filters, will always guarantee the best results in purifying and cleaning the indoor air.
